To all whom it may concern Be it kriowntiiat I, SAMUEL M. COFFMAN,

a citizen of the United States, residing at Kansas City, in the county of Jackson and 5 State Yof Missouri, have invented certain new and useful Improvements in Vending- Machines, of which the following isa specification.l

" My invention relates to coin-controlled andwhile susceptible to otherqpurposes it `is/particularly adapted to vending postage stamps, theater tickets,

railway tickets, etc., arranged in web tornif The invention lembodies stamp selecting i5 means to be controlled by coins of' differentl denominations, so that a stamp, or

stamps. equal in value to the inserted coin will be delivered to the purchaser at each operationof the machine.

L- The invention further provides for feed.l

ing altof the wehs simultaneously to have stamps ysevered therefrom on the insertion of a coi-ii of the proper denomination, and it also provides for 'i'ceding one web while 25 the companion webs areeheld stationary, so

that stamps will not be severed from the latter when a coin of less denomination is inserted.

Other features of the invention will here- 'inai't'er appear, and in order that said 1n` ventioii may be fully understood, reference will now be made to the accompanying drawings, in which:
